"qt creator needs a compiler setup to build windows"

Hello, and thanks for reading
I have installed Qt from a setup named 'qt-opensource-windows-x86-msvc2013_64-5.5.0.exe', from which I infer that this version is setup to use the C compiler in Visual Studio 2013. Mt question is whether it should be backward compatible for older version of VS (I currently have 2012). If so, what do I need to do to get Qt Creator to recognize the compiler? I have tried under Tools | Options | Build & Run to select one of the auto-detected compilers (MV C++ Compiler 11.0 (etc), but I can never get it to show up in the compiler window under the 'Kits' tab when I select on the auto-detected kit name.
